Specification of Letters Patent.

I Patented Mar. 29, 192i.

Application filed June 9, 1915. Serial No. 33,082.

T 0 all whom it may concern:

Be it known that we, EARL H. Snvenns and Roy LOFFLAND, citizens of the United tates, residing at Helto-nville and Northington, in the counties of Lawrence and Greene and State of Indiana, respectively, have invented certain new and useful Improvements in Silos, of which thefollowing is a specification, reference being had therein to the accompanying drawing.

Th s invention relates to certain new and useful improvements in silos; the object being to provide a silo which is formed of mterlocking double tongued and grooved cement staves arranged 'with break-joints in such a manner, that the staves at their abutting edges are interlocked so as to form a very strong and durable silo, and at the same time a. tight joint is formed so as to exclude air and moisture.

Another object of the invention is to provide a silo which is formed of staves provided with acute angled edges each edge having a pair of grooves and apair of tongues which are adapted to interlock with the abutting edge of the adjacent stave, the angle of thefedges of the respective staves, determining the diameter of the complete silo whereby by changing the angle of the edges of the staves, $1103 of various diameters can be formed.

Another object of the invention is to provide a stave silo in which the staves are provided with. flat faces in order to reduce the cost of manufacturing the same.

Another object of the invention is to provide a silo in which the door frames are formed of cement blocks reinforced in such a manner that exceedingly strong and durable frames are formed; the side edges of which are also provided withdouble tongues and grooves interlocking with the grooves and tongues of the adjacent staves.

A still further object of the invention is to provide a stave silo in which the staves are interlocked and held rigid in position, without the use of mortar.

()ther and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.

In the drawings Figure 1, is a vertical section through a portion of a silo showing the manner of constructing the same according to our improved invention;

Fig. 2, is an enlarged horizontal section through a portion of a silo showing the manner of constructing the door frames and doors therefor;

Fig. 3, is a perspective of a portion of a 8110- showing the door frame in position in respect to the abutting staves and the mannor of fastening the door within the frame; and

Fig. 4,, is a detail elevation showing the manner of fastennig the hoops.

Like numerals of reference refer to like parts in the several figures of the drawings.

In constructingasilo in accordance with our invention, a circular base of concrete is formed in the bottom of an excavation approximately fifteen inches wide and with the upper surface thereof thirty-six inches below thesurrounding ground, the circular openingformed by said base being provided with a cement bottom.

Upon the center of this foundation 1, a row of staves 2 and 3 of alternate lengths approximately one and one-half feet and three feet respectively, is placed on the edge forming the base row of staves, these staves being formed with acute angled edges, each stave having on its edge, a pair of tongues 4i and a pair of grooves 5 into which the tongues of the adjacent staves are adapted to interlock so as to form a tight joint and it will be seen that by forming staves with different angles, silos of different diameters canbe constructed. 7 1

These staves are formed approximately twelve inches wideand upon the first row of staves, an additional row of staves all of thesame length, is placed so that when the complete silo is formed, the top and bottom rows of staves constituting the same will be formed of alternating lengths of staves and the intermediate staves will be all of the same length, whereby a silo is formed with break-joints.

Arranged on the base or foundation, is a flat spacer block approximately thirtysix inches square and three inches thick, which extends to the ground level and forms a closure for the door frame opening which.

is arranged in the silo when the same is be ing constructed and into which is placed a same are being constructed and each door is provided with a reinforcing plate 10 carrying a threaded stud 11 on the end of which mounted a fastening bar 12 secured in position thereon by a nut 13 said bar being adapted to engage the outer faces of the door frame when swung into the positions shown in Figs. 2 and 3, in order to securely fasten the doors within the frames so as to form a tight joint, and it will be seen that these fastening. members or bars can be swung into such a position that the doors can be removed from the side of the silo as the silage is removed therefrom.

At intervals, circular hoops 14 are placed around the silo thus formed, the ends of said hoops being threaded and extending through castings 15 and are provided with nuts 16 for placing said hoops under ten sion so as to hold the staves firmly in position.

The inner face of the silo is then brushed with an acid-resisting cement so as to completely'close all of the cracks, although we have found that in constructing a silo in accordance with our invention, the joints between the abutting sections form com plete closures at that point so as to exclude air and moisture without the use of this additional inner coating and, therefore, we do not wish to limit ourselves to the use of such a coating as the silo can be constructed and used togood advantage, without such a coating.

From the foregoing description, it will be seen that we have provided a silo in which the staves are interlocked at the abutting The flat spacer blocks are' the silo as herein shown and. described in connection with the door construction, the doors are interchangeable and can be securely fastened in the door frames or within the vertical door opening in case the silo is constructed without a door frame.

We claim:

A built-up circular silo comprising a circular concrete base embedded in the ground below the surface thereof, a plurality of flat staves of alternate length, arranged on said base, having horizontally disposed upper and lower edges and acute angled side edges, each stave having on its angled edge a pair of tongues and a pair'of grooves, adapted to interlock with one another, a

series of rows of similar constructed staves all of the same length, arrangedaboveth'e first mentioned row to form break joints between the respective staves, a flat spacer block having acute angled edges, provided with tongues and grooves arranged on said base, having itsedges interlocked with the adjacent staves, a plurality of superposed flat door. frames having horizontally disposed upper and lower edges, and acute angled side edges provided with spaced tongues and grooves, arranged on said spacer block, having their edges interlock with the tongues and grooves of the adjacent staves, the upper and lower edges of the door frames being out of horizontal alinement with the upper and lower edges of the staves, and circular hoops arranged around said staves and door frames. y

In testimony whereof we hereunto afiix our signatures in the presence of two witnesses.
